These are the slides I used for lecture in spring 2019. When I lecture, I go through as much material as possible at each lecture, subject to the constraint that everyone follows what I'm doing. The speed at which I go is therefore dependent on the composition of each year's class and the questions that arise. As such, the slides below are not broken up into distinct weeks (I seem to go through roughly 15-20 pages in a weekly session lasting almost 2 hours, but issues and topics not represented here are covered most weeks).

Separate PDF versions of the slides appear for teaching (i.e,. with pauses, etc.) and as a handout for printing. (A warning about the handouts: they're created automatically and so so occasionally don't accurately represent what the page looks like if you click through the slides for teaching.) I update this material almost continuously while I teach. I'd very much appreciate if you would contact me with any comments, corrections, or suggestions.
